The contactless measuring of the dimensional attrition of the cutting tool and roughness of machined surface

摘要

Quality is the main objective of production and includes all attributes of the manufactured product. The quality is understood as a summary (measurable quantities and characteristics) of the product determining its capability to meet the needs, fulfil functions, and have a utility effect. An important technological element is the control of cutting tools during production and use in the production process. Control and scanning attrition of the cutting tool has a double benefit. On the one hand, the shape, dimensions, and micro-geometry of functional surfaces is controlled and on the other hand, the condition of the functional surfaces that are relevant to functional requirements is checked. Therefore, it is logically concluded that the attrition is an undesirable change of the surface or dimensions of the solids which must be constantly controlled to achieve the desired quality of production. The article describes the design of devices for contactless attrition measuring of the cutting tool and roughness of the machined surface using an optical sensor. The proposed device can reduce the costs of production control and improve the quality of production using universal lathe machines.
